Psyren

Ageha Yoshina, a self-assured high school student, offers his services to others for a fee. His life takes a turn when he discovers a mysterious calling card with the word "Psyren" while on his way home from a job. The next day, he finds that his classmate Sakurako Amamiya has the identical card, leading to a series of events that draw him into a game of life and death. After Sakurako's disappearance, Ageha's search for answers leads him to call the number on the card, prompting a series of cryptic questions from a mysterious voice, ultimately offering him a choice to participate in the Psyren game. With the ability to wield "PSI," psychic powers, Ageha joins forces with Sakurako in a desperate bid to return home from a world inhabited by monstrous "Taboo" creatures.
